SPECIFICATION forming part of Letters Patent No. 693,843, dated February 25, 1902.

Application tiled May 14, 1901.

To a/Z/ whom t 711160,77/ concernk Be it known that I, MARK A. DEES, a citi-V zen of the United States, residing at Mosspoint, inthe county of Jackson and State of greatly enlarges the weighing and computing capacity of scales of this type and at the same time provides a compact, simple, and economical construction.

In my application, Serial No. 3i,793, filed October 29, 1900, is describedl an improvement in platform computing-scales of that variety in which both the weight and value of the article weighed are automatically and conveniently indicated; and my present invention, which is an improvement upon the construction described in said application, is'designed to enlarge the weighing and computing functions ofsaid machine, simplify and effect economy in the construction thereof, and generally adapt the invention to a greater field of usefulness. l f

My improvements are applied to any ordinary or approved form of scales of the class mentioned, and much of the mechanism'incorporated herein need not necessarily be described, it being well understood by those skilled in the art of scale manufacture. It will also be seen that several features and combinations incorporated herein are included in the device described and claimed in my aforesaid application, Serial No. 34,793.

What is termed in my said former application the flarge cylindrical casing is in this instance provided with four internal computing-cylinders, which are adapted to be geared together in pairs, so that both cylinders of either pair may be revolved simultaneously. When either of said pairs of cylinders thus geared together are revolved, theV taining to that pair of cylinders.

`Serial Nn. 60,214, (No model.)

other pair is locked by means of stops per- The two pairs of geared cylinders are locked as a series at all times when not connected with the poiseoperating device of the computingbeam. While one pair of cylinders is always geared together,onlyone cylinder of the pair is intended to be used for computations at one time-tl1at is to say, I may use a cylinder of the pair which will compute values of from one-sixteenth to six and one-fourth pounds for the upper or small platform or the other one of the pair which computes values on weights of one-fourth to twenty-five po unds for thelower or large platform. Thus while both the upper and the lower platforms are not supposed to be used at one time, the cylinders of the pair being geared together so as to rotate simultaneously, either platform may be used,the one for lighter and the other for heavier weights. Where still heavier articles a-refto be weighed, the other two cylinders or pair of the series are brought into position, the gear of one of them being caused to engage with tlie gear of the poise-operating device of the computing-beam when said lastmentioned pair of cylinders may be rotated, so that, for instance, by using one values on weights of, say, from twenty live to fifty pounds maybe weighed upon the lower platform, or by using the other cylinder computations of values may be made from, say, fifty to seventy-five pounds on the same platform. The advantage of this arrangement is that should there be an article weighing less than fifty pounds or one in excess of iifty pounds weight both cylinders will be in gear, so that either may be optionally used.

The scale-beam is, as in other scales of this description, composed of two members-that `is to say, it includes the main beam and the tare-beam. Both beams are graduated in precisely the same manner, each being provided with two series of graduations, an upper and a lower one. The purpose of the lower series of graduations on each beam-viz., from zero up to twenty-five pounds-isto-permit the weighing of articlesup to that weight on the lower platform without the use of the ordinary counterweight, while the purpose of the upperseries of graduations oneachbeam- Viz., from zero up to six and one fourth Ioo pounds-is to allow the weighing of articles up to that weight on the upper platform without the employment of a counterweight.

The weight designating and computing members of the upper and lower platforms are arranged in the proportion of four to one. Thus if the poise on the main beam is at five pounds upon the upper series of figures thereon a weight of twenty pounds on the lower platform would balance the poise, as will be seen, the figure 20 being immediately below the figure 5.

In the accompanying drawings, in which some of the figuresrare upon enlarged scale, Figure 1 is a front elevation of my invention, showing the poise of the tare-beam (the only one here visible). at zero and the poise of the main beam adjusted for a given weight. 2 is a plan of Fig. 1. Fig. 3 is aplan, mainly in section, showing details of the platformhanging gear and the standard forming the fulcra for the two beams--viz., the main and tare beams. Fig. 4 is an end view showing the upper and lower platforms of the scale furnished with scoops, an end of the cylindrical casing containing the computing-cylinders being provided with a computing-chart adapted to be used as hereinafter specified. Fig. 5 is a vertical transverse section through the longitudinal center of the frame, lower platform, computing-cylinders, and the casing. Fig. 6 is a section on the line 1 1 of Fig. 2, showing the four computing cylinders geared together in pairs, either pair being capable of rotation by means of the operatinggear, and also showing locking devices, hereinafter described. Fig. 7 is an enlarged view of the locking device. Figs. S, 9, 10, 11, 12, and 13 are enlarged views of various details, hereinafter described. Fig. 141s an enlarged view showing the cylindrical casing and portions of two of theinclosed computing-cylinders with the price-scales used in connection therewith attached to the casing, as also the gearing used with the cylinders. Figs. 15 and 16 show different parts or surfaces of the cylindrical casing with a fixed price-scale for each section of the surface. Figs. 17 and 18 are end views of the cylindrical casing, showing computing-charts used in connection with fixed price-scales. Fig. 19 is a view of a detached detail of the connection between the small platform and the hanging-gear.

Similar numerals of reference indicatesimilar parts in the respective figures.

1 is the ordinary base or foundation having the upper and lower platforms 2 and 3, the upper one being preferably of transparent glass, and 4 is the main beam. The poise of said beam is represented by 5 and is adapted to be mechanically adjusted from any fixed point. The main beam 4 stands in parallel relation to the ordinary tare-beam 4a, upon which is adapted to slide the poise 5u. Both beams, they being rigidly attached, are suitably mounted or have their fulcra in brackets G of the standard '7 and have appropriate Fig.A

unions with the platform-hanging connections. (Shown particularly in Fig. 3 and which will be hereinafter more particularly referred to.)

An important feature is the arrangement by which the poise of the tare-beam may be adj usted and held in such position as to balance either the lower or upper platform when the scoop for either is used. To provide for this, the outer or tare beam is provided with an aperture and the poise on said beam with a spring-catch, by means of which the poise can only be locked at that point, this provision preventing the danger of mistake in providing for the tare in adjusting the poise for either platform. It will be understood that the scale is complete with the lower and upper platforms without the use of scoops and that where scoops are not used the poise on the tare-beam will be pushed back or adjusted at zero and that when scoops of properlyproportioned weight-here four to one-for the respective platforms are used the poise on said beam will be moved so thatits catch will lock with the beam, when, as before stated,

the scale is then in condition for the use et' either platform.

Fig. 13 shows the poise for the tare-beam with its spring-catch 49 adapted to be locked in an aperture of the tare-beam 4, whereby the latter maybe adjusted and held in a position adapting it to balance either the lower or upper platform when a scoop for either is employed, the scoops being, as aforesaid, proportioned in the weights of four to one. It will be understood that the spring-catch 49 is only employed when the scoops are used, for where buckets or other tare are furnished, as by the buyer,the poise of the tare-beam will of course be adjusted correspondingly, as will be readily understood. y

Upon the top of the base 1 (right-hand side of Fig. 1) is a standard 8, having a slot S, Fig. 8, for limiting the movement of the outer end of the combined scale-beam, which in this instance is a continuation of the tarebeam 42. The standard Salso forms the support for the guiding devices of the rack-bar 9, there being a rod 10 extending therefrom to the standard 7. ln bearings of the standard 1l is mounted a short shaft 12, having a hand-wheel 13, the shaft carrying a bevelgear 14, which engages with a similar bevelwheel15, mounted upon a shaft 16, having one bearing in the standard 11 and its other in the standard 3. Upon the end of the shaft 1U is a hand-wheel 18. The short shaft12 earries a spur-wheel19 adjacent to the bevelwheel 15, which spur-wheel engages with the teeth of the rack-bar 9. At the opposite end of the shaft 16 is a spur-wheel 20, which is adapted to operate the internal computingcylinders, as hereinafter explained.

From the rack-bar S) extends upwardly a short curved arm 21, to which is pivotally secured a rod 22, having loose connection with the poise 5 of the main beam.

The connec- IIO tion or arrangement is substantially the same kas inthe device described in'my said former applicatiomwhereby the rotation of the shaft pull 9d, by means ofv which the rack-bar, poise, and computing-cylinders may be rapidly moved without the employment of the hand-wheel 13 or 18. f

The shaft 16, which, as stated, has its bearings in the standards 11 and 8, is so arranged thatV the spur-wheel 2O may be engaged with and disengaged from the gearing of the internal computing-cylinders. To accomplish this, the standard 8, Figs. 1 and 8, is provided with a slot 23, in which is mounted the boxbearing 24 of the shaft 16, said box-bearing being normally projected forward by means of a spiral spring 25, surrounding a pin 26,

having a head 27. The force of the spring 25 will normally keep the spur-wheel 2O engaged with the gear of one of the internal computing-cylinders when in position to be so engaged, and at such time a lip 28, integral with the box bearing 24, will enter one of the notches 29 (of which there are two) in the end flange of the cylindrical casing 30, of which liange a fragment is shown in Fig. 8, the entrance of the lip into said notch locking the cylindrical casing against rotation.

When it is desired to disengage the spur 2O from the gearing of one of the four computing-cylinders inclosed or mounted within the casing 30, the poise 5 of the main beam is by the rotation of either hand-wheel (or by the agency of the handle or pull 9d) carried to the right-hand extremity of the main beam 4, the rack-bar 9 being simultaneously moved. rlhe pin 9 of said rack-bar now striking the under inclined'face 31 of the latch 32, Fig. 11, said latch is raised and released from the rear of the box-bearing 24, (see Fig. 8,) so that the operator by pulling backward the handwheel18 may withdraw the spur-gear 20 from the gear of an internal computing-cylinder, the outward movement of the shaft being provided for by its length and the distance between its bearings. At the same time a slot 20 of the spur-wheel 20 having been brought opposite a finger 33, proj ecting'in wardly from the standard 8, Fig. 10, said iinger enters the slot, and simultaneously with such action the head 27 of the pin 26 is drawn far enough from the outer face of the standard 8 to allow a gravity-latch 34, pivoted to said standard at 35, to fall between the standard and the inner face of the pin-head, thus preventing the pin 26 and its integral box-bearing 27 from a return movement, which otherwise would be In Figs. 1 and 2 is shown connected with the rack-bar 9 a handle or.

lpin 56. 'gular seat or depression 57, a stop-face 58,

induced by the force of the spring 25. Thus the poise 5 of the main beam 4 is locked atits extreme right-hand position or when at'the iigure 25, and the shafty 16 not being capable of revolution, the spur 2O being locked by the finger 33, no movement of the rack-bar 9 or poise 5 can be effected. The vspur-wheel 2O being now out of engagement with a gear of any computing-cylinder, the cylindrical casing 30, carrying the computing-cylinders,

may be rotated by means of its hand-wheel 36 for the purpose of other computations, as

lwill be explained hereinafter.

Four computing-cylinders 38 39 4041 (see Fig. 5)'are assembled or mounted within the cylindrical'casing 30 and, as stated, geared together, Fig. 6, in pairs, so that there is always coincident rotation of two of said cylinders instead of one, asin my said former invention. Thus I here provide means for simultaneously adjusting the poise 5 of the main beam 4 and revolving two cylinders, one of which computes values on weights of, say, one-fourth to twenty-live pounds for the lower or large platform 42, while the other computes valueson weights from one-sixteenth to six and one-fourth pounds on the upper or small platform 43. Either the lower platform or the upper platform may be used, and the computing-cylinder for each will, in connection with the prices per pound indicated upon the price-scales attached to the `cylindrical casing 30, compute the value of a weight put upon either platform. The operator may thus quickly use either platform without any special adjustment of the cylinder therefor or transfer the article weighed from one platform to the other or use either optionally.

I further provide means whereby the pair of geared computing-cylinders not in use will be fixedly held and the pair in use automatically checked or stopped at the end of a complete revolution less a quarter of an inch, as explained below. Fig. 7 indicates, on enlarged scale, the means employed, the same means being shown on smaller scale and in action in Fig. 6. 51 represents ablock pivoted within-the cylindrical casing 30 at 53 and attached to a spring 54, having a sliding connection 55 with the casing by means of the 'lhe block 5l is provided with an anand a projecting portion having a rounded or circular surface, as indicated at 60. A spoke of one gear of each pair is' furnished with a ratchet-tooth 52 of one-quarter of an inch in greatest width, which at the proper time engages the angular seat or depression 57, as

IOO

IIO

shown in Fig. 7, or the stop-face, as at the right of Fig. 6. The gears 38a 39fL are supposed to have completed a full revolution less the quarter of one inch referred to, and it willvb'e seen that the ratchet-tooth 52 has engaged the stop-face 58 and that the spring 54 has exerted its force so as to tilt thel block 51 upon its pivot 53, thus causing the round- ISO ' wheel 20.

ed face 60 of said block to bear upon the tooth 52. Now supposing the'gears 38 39 are to be revolvedin the opposite direction, so as to bring the poise of the main beam from zero to twenty-five pounds, the tooth 52 will slide over the rounded portion 60 of the block, whereupon the block will fall or tilt upon its pivot 53, the spring 54 straightening out, and when the gear 38 has completed a full revolution less the quarter of one inch the opposite side of the tooth will engage the in clined seat or recess 57 of the block, thus checking the movement of the gearing.

In my said former application'each one of the internal computing-cylinders is described as making a full revolution when the poise moves the full length of the main beam. Such arrangement does not provide a zero-value column.v Inkmy present invention t-he construction is such, owing to the use of the tooth 52, that each gear is stopped one-quarter of an inch short of a full revolution, it being apparent that a zero-value column is thus provided for.

Vhen the two pairs of gears are not in use, as when the casing 30 is to be revolved upon its axis, the two sets of gears are locked, as shown in Fig. 7. The disengagement or unlocking of the cylinders when again brought into gear with the spur-wheel 20 is accomplished by exerting a little extra force in revolving either hand-wheel 15 or 18 or upon the handle orpull 9d, so as to'throw the tooth 52 from its seat 57.

In addition to the stopping devices above described I employ at each end of the main beam 4 a stop for the poise, that at the outer end of the beam being indicated by 4", while the stop at the other end is formed by a shoulder 4c of the fulcrum-block of the combined beam. By the means described the cylinders and poise are simultaneously checked or stopped at the extremity of each movement, thus relieving the several parts,and especially the rod 22, from strain.

It is important that the poise on the main beam, as also the internal computing-cylinders, shall at all times be locked in the exact positions occupied by them at the moment of the separation ofthe spur-wheel 2O from a gear of a computing-cylinder, so, that both said poise and the cylinders shall indicate the same Weight. Means for elfecting the locking of said poise are found in the finger 33, Fig. 10, acting in conjunction with the spur- Now when the cylindrical casing 30 is revolved, the lip 28 being withdrawn from the notch 29 of the iiange of the casing 30, said lip will bear upon the edge of the flange, it being circular throughout, the finger 33 being thus kept in engagement with the spur-wheel 2O and locking the poise, even though the latch 34 be accidentallylifted, and no engagement of the gearing can occur until the lip 28 reaches a notch of the flange.

Fig. 14 shows the slotted cylindrical casing 30, a price-scale being mounted thereon parallel and adjacent to cach slot, they being shown by 44 441. The view also shows portions of the internal computing-cylinders 38 and 30, said portions being visible through the slots 45 451L of the casing 30. The cylinder 38, which is the only one designed to bc employed in connection with the upper platform 43, is here represented as exhibiting a line of figures which are computations on articles weighing four pounds and ranging from prices of one cent and a half up to eighty cents. Thus the figure 4 is found both at the right and left columns containing the figures indicating the weight of material entering into the computation and the sum three hundred and twenty immediately under the gure 80 on the fixed price-scale 44, indicating that four pounds of merchandise at eighty cents a pound will amount to three dollars and twenty cents. In further illustration it will be seen that the figure 9 in the line of computinggures is immediately under 24 upon the price-scale 44, indicating that four pounds of material at two and onefourth cents a pound will cost nine cents.

The figures specifying the prices per pound and fractions thereof are arranged in two columns, the figures alternating in arrangeA ment, the object of this being to prevent confusion of figures by placing them too closely together.

`With respect to the cylinder 39 (also seen in Fig. 14) the same arrangement is carried out, except that four times the amount of material (or four times the unit of weight used in the above-explained use of cylinder 38) iS here employed in illustration and that the prices on the price-scale 44 used in connection with said cylinder 39 rango from one and one-half cents to forty cents. In illustration of the use of the cylinder 39 take, for example, sixteen pounds of merchandise at forty cents a pound, the cost of which will be found to be six dollars and forty cents, and take, further, the example of sixteen pounds IOO IIO

at four and three-fourths cents, the cost of Y that amount of material being seventy-six cents.

The functions of the cylinders 40 and 4l are precisely the same as those described in connection with cylinder 39, the only difference being that they are intended to compute for weights from twenty-five to fifty pounds and from fifty to seven ty-f ve pounds, respectively. The cylinder 38 is arranged to compute by sixteenths of pounds or ounces and the cylinder 39 by quarters of pounds. The cylinders 39, 40, and 4l are used exclusively in connection with the lower platform.

Figs. 15 and 16 show views of ditferent parts or surfaces of the cylindrical casing 30, intended to be used With a fixed price-scale 37 or 37L for articles of greater weight than can be computed by the internal cylinders. Fig. 15 exhibits a portion of the surface of said casing for computing values on bushels, for example, of thirty-two pounds or of sixty pounds. The cylindrical casing 30 is divided into four sections for determining the prices of bushels of thirty-two pounds, forty-six pounds, fifty-'six pounds, or sixty pounds; but for con'venience only such portions as relate to bushels of thirty-two pounds and sixty pounds are illustrated.

Whenmore than seventy-five pounds are weighed, as the internal computing-cylinders will not compute above thatigure, the cylindrical casing must be disconnected, as already described, and revolved so as to use it in connection with the fixed price-scale 37 or 37".

Referring to that section of the casing and its fixed price-scale 37'used for indicating the prices per bushel of thirty-two pounds, it will be seen, Fig. 15, that on the left-hand side of the chart there is a column of figures running from "175 to 290, which sufficiently indicates the number of pounds to be weighed, and that in horizontal arrangement to said column of: figures are other rows containing numbers, one set running from 125 to 313and the other from 1577 to 391. In connection with the casing 30, as has already been stated, is employed the fixed price-scale 37 or 37a. (Indicated in Figs. 15 and 16.) This fixed price-'scale bears upon either end the words No. lbs, and arranged in horizontal rows are certain iigu res (see the left-hand section of Fig. 15) running from 15 to 60 in alternating columns, so arranged' for, convenience in reading. These figures ranging from 15 to 60 indicate the price per bushel of thirty two pounds. At the right-hand section of Fig. 15 the respective figures indicated upon the fixed price-scale 37 relate to bushels of sixty pounds.

Let it be supposed that two hundred and fifty pounds of oats at twenty-five cents a bushel (of thirty two pounds) have been weighed. The cylindrical casing 30 having been released,as above stated,is turned by the use of the hand-wheel 36 at one end thereof until 250 pounds on the marginal column is brought so as to be in line with and adjacent to lthe upper `-edge of the fixed price-scale 37. The operator will then run his eye along the upper edge of the said fixed price-scale until it reaches the figure 25, when opposite the 250 and immediately above the 25 will be found 196, indicating that the price of two hundred and fifty pounds of oats at twenty-five cents per bushel of thirty-two poundsis one dollarand ninety-sixcents. The operation will be the same in the` use of that section of the chart surrounding the casing 30 relating to abushel of sixty pounds or of forty# six or fifty-six. `When the casing 30 is thus employed as a computer, the internal computing-cylinders are locked, as seen in Fig. 7, either pair of said internal cylinders being only capable of rotation when brought into gear with the poise-operating mechanism.

Referring to Fig. 5, it will be seen that the cylindrical casing 30 is iiattened at two sides, as indicated at 48. This arrangement brings the parts of said casing containing the slots and the price-scales parallel thereto in close proximity to the peripheries of the respective pairs of internal com pitting-cylinders, and the figures upon the cylinders and those upon the scales are situated practically at the top of the casing, whereby ready and convenient reading is permitted. Were the slots in the casing placed at the points where the peripheries ot' the internal cylinders most closely approach the cylindrical wall of the casing, the slot to be used, say, for the cylinder 38 would be about on line with the shaft 16 and that for the cylinder 39 too far in the rear to enable the operator to conveniently effect the computation." This feature of my invention is an important one, bringing the figures of the computing-cylinders and those upon the price-scales toa position the best adapted for convenient reading by both seller and buyer.

Figs. 17 and 18 show the respective ends of the cylindrical casing 30 provided with computing-charts used in connection with fixed price-scales A6l 62. Fig. 17 shows the chart arranged for computing by the dozen-as, for instance, eggs, dtd-and also fractions of dollars worth, as where a merchant sells sixty pounds of goods for a dollar and a customer should call for sixty-five cents7 worth, when he would get thirty-nine pounds.

Fig. 18 shows the chart adapted to compute by the hundredweight, used also in connection with a fixed price-scale, which lchart may be employed in computing the price of such articles as bran sold by the hundredweightfor instance, where a merchant is selling bran at seventy-five cents a hundredweight and a sack of bran on being weighed is found to weigh seventy live pounds its cost being fifty-six and one-fourth cents, or, as here indicated, fty-seven cents.

55, Figplti, shows/the connectionbetween IOO IIO

the small platform and the hanging-gear of the scale mechanism, its peculiarity being that it is twisted, so as to bring the uniting-eyes at a moved upon the counter. Spirit-levels, Figs.

1 and 3, are shown by 63 64 at a right angle to each other, and in Fig. 5 are shown wheels 65, mounted in adjustable casters 66, each having a threaded pin 67, which works in a nut 68, integral with orattached to the frame 1. The threaded pin 67 is provided with a hand-wheel 69, the pin and mounting of the wheel being swiveled, so that the adjustment of the level of the scales may be made by turning the hand-wheels 69.

While the scale herein indicated is only .capable of weighing twenty-five pounds without counterweights, its capacity may be increased indefinitely bythe addition of suitable counterweights, the mode of use of which is so well understood that it need not be described.

The operation of my invention will be fully understood from the preceding description and by those skilled in the art of scale construction as well as by users of scales of this class.

By my invention, each chart differing from all others in its prices per unit and Weights and the whole system of independent charts regularly advancing from a low fraction of a pound and a low fraction of a cent per unit up to any desired weight and to the price of4 the most expensive goods ordinarily sold over the counter, the greatest diversity and extent of computations are possible, the mechanism enabling such results to be effected being confined in most compact and limited space.`

While I have here described and shown what is considered to be a sim ple and efficient device and one which is an improvement upon the invention described in my aforesaid application Serial No. 3I,793, I do not limitmyself to the special mechanisms, constructions, and combinations herein Vspecifically described and illustrated, it being evident that modifications thereof having the same or substantially the same functions may be devised by a skilful mechanic without exercising the faculty of invention, and such unimportant deviations from what is herein specifically described and illustrated not involving invention I consider as within the terms of my claims.
